Question

SIMPLIFY- Algebra
-5-2x-3-x
I have -7x-3 so far but I’m not sure

Answer 1

`-3x - 8`

Explanation:

The only thing you have to do is combine the like terms.

`-5-2x-3-x` (combine the x values and the 5 and the 3)

`-3x-8` (That's all)

I'm not really sure what you did but I might have an idea. You might have subtracted the -5 and the -2x, but you cannot do that because they are not like terms and by that I mean that you have to subtract the -x from the -2x. The same goes for the -5 and -3 you have to keep those two together and subtract them. When you do that you will get -3x - 8.

Answer 2

Explanation

• Given the expression.

`- 5 - 2x - 3 - x`

• Simplify

Remind that a constant cannot add up or subtract with a variable term. Instead we just leave them.

`- 2x - x - 5 - 3 = - 3x - 8`

We can add up the same term. A constant can only add up or subtract with a constant. A variable term can only subtract or add up with the same variable term. (you can add or subtract x+x BUT not x²+x as both have different degree.)

Answer

`\large \boxed{ - 3x - 8}`
